Cannot log in or key in. - Hitachi LifeStudio HLSDBUB10001BBB 1 TB USB 2.0 Hard Drive

hi

if it a scientific calculator there should be a surd key ( look like a square root symbol, other way to get a square look for the "^" key that the exponent or power key do the follow type in the number be square rooted and press the "^" key and type "(1/2)" ( without the "" of course) and you will get the square root of your number. You can use the log and ln keys as well

type in your number you want square rooted and press the log or ln keys divide the result by 2 press the anti log key use might have press the 2nd key or shift key and press the log ( or 10^ key) or ln( or e^ key) the 10^ key and the e^ key change log to normal numbers

i.e.

square root 9

type 9 press log to get .954242509 for a result
divide by 2 to get .477121255 press the 10^ key to get
3 for a answer.

For common log, use the LOG key. For natural log, use the LN key. In either case, enter (or calculate) the value of the argument and then press the appropriate key.

To calculate the common log of 2, press 2 LOG =

To calculate the natural log of 2, press 2 LN =

What you call the antilog is also known as as the power function. More specifically, the inverse of a decimal log is the function 10 to a power, (10^x) It shares the same physical key as the log function. If the calculator has a key marked [LOG] you have to press the [2nd or SHIFT] key followed by the [LOG] key to activate the anti-log.

For natural log (logarithms in base e) the antilog is the exponential function (e^x). It shares the same physical key as the [LN] function.

For common logarithm use the LOG key just below the blue 2nd key. For natural logarithm use the LN key just below the LOG key.

In either case, press the appropriate key, then type in the expression whose log you want, then the ) key. Type in whatever else there might be in the total expression, then the ENTER key.

For example, to calculate the natural log of 2:
LN 2 ) ENTER

For common log use the LOG key. For natural log use the LN key. These keys are just below the 2nd-shift key at the upper-left corner of the keyboard, and take the log of the expression on the display.

Yes, there is a [LOG] key to calculate decimal logarithms (logs in base 10) it is marked LOG, and another key marked [LN] to calculate the natural logarithms (logs in base e).
You enter a positive number, then press the appropriate log key (LOG or LN) and the result will be displayed.

Since I do not know what Kenko calculator you have I will remain general.

Locate a key marked log (for common decimal logarithm)
Try the two options. One of them is bound to work

1. Enter a positive number and press the key marked LOG.
2. If that does not work, press the LOG key and then enter a positive number. If the calculator displayed log( , with a left parenthesis, insert a right parenthesis before pressing the = key.

To calculate the natural logarithms (LN), look for a key marked with LN and proceed as for the common logarithm. I am sure that the syntax (key sequence) that works for the common log will work for th natural log.

If no key is marked on top of it with LOG or LN, it may be because those markings are ON the body of calculator. In that case the functions are accessed by pressing a key marked SHIFT or 2ND, or 2ndF before the function LOG or LN.

Use the log function (common logarithm). See screen capture for markings on key.

To evaluate the negative of a logarithm
Enter the number (argument) of the logarithm
Press the = key to have it calculated.
While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation
log(1/a)=-log(a) .

Your example

3 [EXP] [(] [+/-] 2 [) ] [LOG][=] [+/-]

[EXP] is the key to enter exponent of a power of 10 :It is a shortcut, so no 10 is entered. Respect the key sequence above.
[ (] left parenthesis to prevent ambiguity due to the negaticve exponent. Just a security.
[)] is the enclosing right parenthesis
[+/-] is the Sign Change key

To use the log function you press the [LOG] key in the middle of the first row of keys.
To use it.
Enter the number the log of which you want to calculate (must be positive)
Press the [LOG] key
Result is displayed.

Ex log(33.54)
33.54 [LOG] result is 1.5255

Once a logarithm has been calculated, use the [+/-] key, the change sign key located between the [.] and the [=] keys, on the bottom row of keys. You must press the change sign after you have calculated the logarithm.

Hi ;

for log base 10 use the the "log" key

example :

log(2) + log(3) = log(6)

enter 2 press the log key you will get 0.30102999 press the '+" key than 3 log you should get 0.47712125 for it Press the "=" or enter and you should get 0.778151250 for a answer than press inv or 2nd log and you should get 6 for a answer

and that all there is to it
